Embodiment Construction

[0060] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0061] Such as figure 1 Shown is a flow chart of an adaptive cruise torque control method according to an embodiment of the present invention. The implementation process of this method will be described in detail below with respect to this figure.

[0062] Here, before specifically describing the execution steps of the method, it should be noted that the electric vehicle in the embodiment of the present invention has an adaptive cruise function, which belongs to the function of comfortable driving control.

[0063] In addition, for an electric vehicle with an adaptive cruise function, the working modes of the whole vehicle include: a normal driving mode and an ACC driving mode. Among them, the normal driving mode is that the driver controls the opening...

Abstract

The invention provides an adaptive cruise torque control method and device and an electric vehicle. The method includes the steps of obtaining the relative speed and time interval between the electricvehicle and a target vehicle in front of the electric vehicle; determining whether there is a braking demand for the electric vehicle according to the relative speed or the time interval; if there isthe braking demand for the electric vehicle, according to the relative speed, determining a target braking demand torque of the electric vehicle; according to the preset priority of modules for torque control, controlling the corresponding module to perform torque control on the electric vehicle so as to cause the actual braking torque output to the electric vehicle to be the target braking demand torque, wherein the modules for torque control include a complete vehicle longitudinal control module, a driving assistance deceleration control module and an electronic stability control system. According to the adaptive cruise torque control method and device, the output torque of the electric vehicle is controlled according to torque control logic of the priority of the modules used for the torque control, not only can the safety of complete vehicle driving be improved, but also driving comfort can be improved, and the control disorder problem that may occur is solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an adaptive cruise torque control method and device and an electric vehicle. Background technique [0002] Adaptive Cruise Control (ACC) system is an intelligent automatic control system, which is developed on the basis of traditional positioning cruise control system. During the driving process of the vehicle, the vehicle is detected by additional detection modules in the forward direction of the vehicle (such as the mid-range front millimeter-wave radar installed at the air intake grille and the front-view camera installed on the interior rearview mirror) Obstacle vehicle conditions ahead, so as to control the cruising speed of the vehicle to maintain a stable following distance. With the adaptive cruise system, the driver does not need to control the accelerator or brake pedal all the time, which can effectively relieve driving fatigue. [0003] However, in the cur...
